I wouldn't say he got "rave" reviews. People were impressed by the sustain, but almost everyone agreed that there was an extreme lack of TONE. I thought the sound clip sounded terrible, but with an MDF body, cheap pickup, and a POD used to record the clip, my expectations weren't very high anyway.
MDF is good for practice and template making, but I'd never use it on a guitar that I was going to gig or record with.
